About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-100
The AirTAC SAIJ32X350-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 250 to 350 mm, allowing you to dial back the nominal 350 mm stroke by up to 100 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa operating pressure.
This variant uses a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback integration. Since the adjuster acts purely as a mechanical stop on the retract end, it cannot hold a load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-100 Is Used
Product Changeovers
Dial the end-stop back by up to 100 mm to instantly accommodate shorter product lengths on a packaging line without changing the cylinder.
End-Position Tuning
Fine-tune the 250-350 mm travel window during machine setup to perfectly time the retract stroke without adding bulky external mechanical stops.
Multi-Format Lines
Ideal for automated lines running mixed product batches, allowing operators to adjust the cylinder stroke quickly during format transitions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-100 the Right Cylinder?
Choose this adjustable-stroke model when a fixed-stroke SAI cylinder cannot accommodate product size changeovers without physically swapping components. The 100 mm adjustment window lets you fine-tune the retract end-position on the fly. If your application requires higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 350 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread still require an external guide to prevent excessive side-loading and premature seal wear. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-100 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 350 mm nominal stroke down to 250 mm. This stop only sets the end position and does not lock or hold the load without live air pressure.
